Description

The Joule Invacyl 90L Indirect Slimline Unvented Cylinder (TRBMVI-0090SFC) is a compact, stainless‑steel hot water storage cylinder engineered for unvented mains‑pressure systems. It delivers 80.44 L of usable hot water heated indirectly via a 316L stainless‑steel coil, providing reliable high‑pressure supply in space‑restricted installations. Dense PU foam insulation, corrosion‑resistant LDX 2101 construction and a 25‑year warranty ensure low standby heat loss and long‑term performance.

Key Features

  • Capacity: 80.44 L actual usable hot water.
  • Slimline stainless‑steel construction: LDX 2101 cylinder for durability and corrosion resistance.
  • Indirect heating coil: 316L stainless‑steel coil rated 15.73 kW with 0.66 surface area for effective heat transfer.
  • Efficient insulation: Dense PU foam to reduce standby heat loss (1.152 kW/24h).
  • Mains‑pressure operation: Max mains water pressure 10 bar; operating pressure 7 bar for strong delivery.
  • Immersion ready: 3 kW @ 230 V immersion specification.
  • Low primary resistance: Coil resistance 0.2 bar; coil max primary pressure 6 bar for efficient circulation.
  • Robust outer finish: Coated mild steel casing for added protection.
  • Safety & compliance: Tested to BS EN 12897:2016; safety valve set to 90 °C.
  • Warranty: 25‑year warranty for long service life.
